STEWART S. KELCHNER, OF EASTON, PENNSYLVANIA.

WATER-MOTOR.

Application filed December 31, 1909.

To all whom it may concern:

Be it known that I, STEWART S. KELCH- NER, a citizen of the United States, residing at Easton, in the county of Northampton and State of Pennsylvania, have invented certain new and useful Improvements in Water-Motors, of which the following is a specification.

This invention relates to improvements in water motors and comprises a motor having a partly rotating reversing driver or piston and a valve action whereby the direction of flow of the driving fluid will be reversed by the piston when it reaches its limit of travel either way.

One of the objects of the invention is the construction of a simple motor having a piston oscillating therein and a rotary controlling valve whereby the piston will be automatically reversed by the piston.

Another object of the invention is the construction of a motor having its packing so arranged that the water or driving fluid will act on the non-wearing side thereof to take up any wear of the packing and to hold the same tightly against the bearing surfaces.

With the above and other objects in view the invention comprises certain combinations, constructions and arrangements of parts, clearly described in the following specification and clearly illustrated in the accompanying drawings, in which- Figure 1 is a top plan view of my improved motor with the upper plate removed. Fig. 2 is a vertical sectional view thereof shown partly in elevation. Fig. 3 is a perspective view of a piston. Fig. 4 is a detail vertical sectional view of an inwardly projecting housing. Fig. 5 is an elevational view of a valve. Fig.3 is another view thereof, Fig. 7 is an elevation of a valve casing, Fig. 8 is a fragmental sectional view T of the valve casing and piston shaft. Fig.

9 is a cross-sectional view of a piston. Figs. 10, 11, 12, 13, 14, and 15 are detail sectional views of a valve casing, valve and piston in different relative positions.

Referring to the accompanying drawings, in-which the invention is illustrated, 3 is a casing of a cylinder wherein a motor piston is operatively disposed. The casing or cylinder 3 is provided. with a top plate 4, hich Specification of Letters Patent.

has an opening 5 for the inlet of the driving fluid. The plate 4 is also provided with a bearing cup 6, in which the upper end of the drive or piston shaft 7 is disposed. The casing or cylinder 3 is formed with an inwardly projecting housing 8, in which a rotary valve 9 is disposed. The valve casing 8 is formed like the segment of a circle and is provided with inlet ports, 10 and 11, which are adapted to register with ports 12 and 13 of the valve 9. The valve 9 formed with a division portion 1-1, whereby the same is divided into two compartments. The lower compartment is provided with two outlet ports 15 and 16, which register with outlet ports 17 and 18 in the casing 8. The upper end of the valve 9 is provided with a pin 19, which moves in a slot or pocket 20, formed in the housing 8, whereby the valve will be held from movement out of the desired limit of action.

Within the casing 3 a shaft 21 is journaled, the upper end thereof being formed hollow and bearing against the cup 22, of the plate 1. The upper shaft end is reduced to form a shoulder and packing 23 is disposed therearound. Against the packing 23 a washer 24 is located. The cup 22 is formed with fluid passages 25, whereby the driving fluid under pressure may enter the cup and force the packing against the inner wall surface of said cup, and in this way effect a water tight connection with the shaft 21.

The valve housing 8 is formed with fluid passages 26 which afford a passage for water under pressure to ports 27, formed in the valve housing, which is provided with packing 28, adapted to bear against the shaft 21 and form, with'the pressure of the driving fluid thereagainst a water tight connection with said shaft. The lower end of the shaft 21 projects through the casing 3 and is secured in place by a nut 29, which bears against packing 30, thus forming a water tight connection with said lower end. The shaft 21 carries a piston 31 which piston is provided with an operating arm 32, which extends on either side thereof, so as to engage the valve 9, which is provided with notches 33 and 34, whereby said arm can partly rotate said valve. The casing 8 is provided with suitable openings through which the operating arm can project into connection with the valve 9. The lower end of the valve exhausts through an outlet port 36, in the casing 3.

The operation of the motor is as follows Water or other driving fluid is first admitted in the casing through the port 5. The valve 9 is so arranged that it will be in communication with either side of the abutment plate but no two sides at the same time. With the valve 9 in the position shown in Fig. 10 the port 13 of said valve will be in register with port 11 of the valve casing and the pressure fluid will be exerted against the piston 31 on the side nearest the inlet port 11. When the valve 9 is in this position the port 17 of the casing 8 and the port 15 of the valve 9 are in register, so that the pressure fluid on the opposite side of the piston can be exhausted. As the piston and the shaft supporting the same are oscillated the arm 32 will be brought into engagement with the recess or notch 34 of said valve 9. When this occurs the valve 9 will be re versed so that the inlet port 12 of said valve will be brought into register with the inlet port 10 of the casing 8, so that the pressure fluid will enter the casing 3 on the opposite side of the piston. This action will cause the piston and the shaft to be driven in an opposite direction. When the ports 10 and 12 are in register the ports 15 and 17 will be out of register. In order to make a water tight connection between the piston and the casing the piston is provided with packing 32*.
